A Clever maker Brian “DoctaBu” Moore has discover that the mystery Wii Sensor Bar was actually nothing more than a simply device sending IR signal to the Wiimote by appox 10 IR LEDs, no actual signal or data is send to the Wii console itself, so he made a home made wireless version of the sensor bar with only 4 LEDs and powerd them by 4 AA batteries!
Great work there!! I think it would be cool to DIY one if I get a Wii too!!!!
